Underfoot for rails, tips and tails to be less catchy on spins and butters if you wanna. Both will affect groomer performance but I can still rip hard east coast groomers on my chronics and they only have edge from in front of binding to the rocker, same for tail
I also spin and butter all my skis, mounts range from -2 to -13, but I like -3 to -8 for park, you may wanna consider a pure park skis and save your atris if it’s in the budget, lotta sales rn especially last years models
Coleg55I’m able to hit 180s and 3s no problem on side hits around the mountain. I’m still getting used to park jumps. And for detuning do you just dull the underfoot? Does that effect groomer performance
